Purpose Ray propagation visualization and optical performance analysis of four different intraocular lenses (IOLs) Methods In this laboratory study, IOLs with designs were assessed: a monofocal AcrySof IQ SN60WF [Alcon], diffractive-refractive bifocal Restor SN6AD1 diffractive trifocal PanOptix TFNT00 extended-depth-of-focus (EDOF) Symfony ZXR00 [Johnson&Johnson]. An experimental set-up water bath containing 0.01% fluorescein solution monochromatic green laser light (532 nm) was used to visualize the rays. Also, evaluated by measuring modulation transfer function (MTF) values at pupil sizes 3.0 4.5 mm on bench OptiSpheric® IOL PRO II (Trioptics GmbH, Germany). Results Both EDOF showed two defined foci for distance near vision. IOL, three distinct distance, intermediate, vision could be visualized. Conclusions The ray technique allows qualitative assessment comparison energy distribution between models. measured Through-Focus Response (TFR) quantitatively confirmed behavior.
